Does anyone have any idea where to change this? I tried modifying the Dwt.setTitle function to replace everything in the incoming text. This worked in that I can manipulate the title from the end of the server name on. However, I can not remove the url.

What OS and browser are you using? I just looked at both FF 2.0 on Linux and IE7 under WinXP and neither shows the URL in the title bar. Both of them show "Zimbra: Inbox" followed by the browser title.
